To all whom t may concern.' f. v I

Be ity lmownthatfl, @ARTE Gr. Grimm a citizen of the United States, residing at Riverside, in the county of Cook and State of Illinois,y have invented new and useful improvements in Uncoupli'ng Devices for Car Couplers, and moreY particularly to devices of this character employed on freight cars and frequently known asy release riggings. i i

lt is the object ofths invention tolprovide a simple and efficient releaserigging comprising but few'parts andv which canloe readily attached to the diderent types` of freight cars y A This particular invention relates tor what is generally known, inY this art as lthe push down type of uncoupling device and comprises two levers having their adjacent ends pivotally mounted on theV same fulcrum. The particulary advantage' of this construction resides in the manner in` which the levers are pivoted -upon the fulcrum. ln levers ofr this general type mounted on a 25 common fulcrum the connect-ion between the levers must allow for the longitudinal movement of the Coupler'head in draft and in huling and thekrotative movement of `the pin lifting lever about the fnilcrumtmusthe limited for the purpose of safety tothe operator. J

The manner of mounting the levers on the fulcrum, in accordance with this invention, provides at the fulcrumV means allowing` play of the free end of the pin lifting lever in a horizontal plane 'without ytransmitting such movement tothe' hande-lever: 1

`Fig.y 11 is aperspective view/of the fulcrumend 4of thepin lever. n 60 In the embodiment of thisinvention .as illustrated the 4numeral l indicates the'end of ay freight car of the non-endv sill type; 2 the strijkingcasting; 3 the coupler head 4 the?l couplerlocking pin eye; 5 the side sill and 6 the hralre mast, yall of which are of usual construction. L f Theauncoupling device comprises an' operating lever '7 and a-pin-lifting lever 8 having their adjacent ends mounted on` a common `fulcrum including a casting 9 mounted on plate `10 depending from;` the underside of the car yend.` The piny lifting lever-` is providedr with an olfset to pass the bralrefmast with its free end portion parallel to the car end.. and is of reduced size, to passthroughand beyond the eye of the lock-r ing pin with theI extremity bent in they form of a. hook. l.Both ends of both levers are preferablyoffset, as shown, so that their extremities y will flie, in parallel horizontal planes which will allow the coupler head to move .hack andV forth transversely without transmitting its movement tothepin lifting lever, provide a more rconvenient man-ner for attaching and mounting the adjacent ends n of the levers on the fulcrumand* adord a ready hand grip orfoot engagement on th free end of the operating lever.,y f

The fulcrumfcasting @comprises na hase plate having `afhollow boss l1 extending `at right angles .therefrom and is provided with a `reduced cylindrical portion l2 atits outer end.. Rectangular' openings 13 are swedged in the adjacent. ends ofthe operating and pin lifting levers through which'is passed a. rectangular i connecting l and .n hearing llolock 14C having a central' aperture adaptedV to pass over and rotateupon the reduced portion' 1:2 ofthe yfulcrum casting-,y thus the connecting loo y and bearing block forms rotative connection havel a non-rotative connection therewith so that the two levers have a unitaryl vertical This connecting and bearing block 14 is provided on the outside along its upper and lower edges with right angular lugs or projections 15 and the block is secured in position by a bolt 16 passing from the rear through the supporting plate `10 and parts 11 and 12 of the fulcrum casting having a washer 17 andnut 118 on the outer end of the fulcrum adapted to be engaged by the outer side of the bearing block. Itis-preferable to arrange the hand operatinglever on the inner side adjacent to the shoulder formed by the part 11. To allow or compensate for longitudinal movement of the free end of the pin lifting lever, the end of this lever about the fulcrum is bent `at'an angle, as clearly shown in Fig. 3, so

that the bend 19 in' the metal is vertical and passesthrough the center of the fulcrum. rllhe lugs or projections 15 on the connecting bearing block may be tapered from the center of the fulcrum towards each end.' However, the thickest portion will be opposite the bend in the pin lifting lever so that movement back and forth vin the direction of the longitudinal center of the car willcause this end of the lever to pivot on thebearing block projections without transmitting such movement to the operating lever. Since kthe bearing and connecting block is of rectangular shape and is received within similar rectangular openings in the ends `of each of the levers a downward movement of the operating lever will cause a corresponding upward movement to the pinlifting lever for unlocking the coupler head. f Y

While this invention is illustrated as applied to a certain type of freight car, itA is readily adapted with but slight immaterial changes for application to other types.

. This application is a continuation of my application ASerial No. 458,501, filed April 4, 1921; certain typical forms of the invention herein disclosed being originally shown and described in said application.

What I ,claim isz' j I 1. A release rigging for railroad car couplers -comprising an operating lever, a coupler lock pin lifting lever, a fulcrum for said levers upon the car, and a combined connecting and Vbearing block which passesy through apertures in said levers.

2. A release rigging for railroad car couplers comprising an operating lever, a

coupler lock pin lifting lever, a fulcrum for said levers upon the car, a combined connectingk and bearing block which passes through apertures in said levers, and means thereon allowing pivotal movement of the pin lifting` lever thereon horizontally independent of the operating lever.

3. A release rigging for railroad car couplers comprising an operating lever, a coupler lock pin lift-ing lever, a fulcrum for said levers upon the car, and a combined connecting and bearing block for said levers upon said fulcrum passing through the ad-' said levers upon the car, a combined connecting and bearing block of rectangular contour upon said fulcrum passing throughk coupler lock pin lifting lever, a fulcrum for similarly shaped apertures provided therefor in the adjacent ends of said levers,land means for retaining said block upon said fulcrum.
